1. a) decrease using mapping the expression f = SM(2,8,9,10,11,12,14) and
implement the real minimal expression in universal logic.
b) With the help of a logic diagram and a truth table, discuss the three to nine decoder.

2. a) Implement the subsequent logic function using an 8*1 multiplexer considering D as
the input and A, B as the choose lines.
b) Design a 4-bit universal shift register and draw the circuit with the provided mode of
operation table.

3. a) How subtraction is done on the binary numbers represented in one's complement
notation provide an example.
